Carolyn Murphy was born in Panama City, Florida and grew up mainly in Northwest Florida, with brief periods in England and Maryland, as a result of her parents’ divorce. Her career began when at the age of 16, her mother enrolled her in a modeling school. Soon, she was modeling locally in Florida, as well as abroad in Japan and Paris. After graduating from Choctawhatchee High School in 1991, Murphy went to New York.

In 1998, she was named VH1/Vogue's "Model of the Year". Barry Levinson chose her for the role of "Dubbie" in his film Liberty Heights. In 1999, she was cited by Vogue as the "Model of the Millennium" and considered a muse by Calvin Klein, landing a contract for the perfume "Contradiction" with fellow Liberty Heights costar, Justin Chambers. She was offered roles in "Pearl Harbor" and many others to follow. Also in 1998, during a photo shoot for Elle magazine, the photographer noticed her resemblance to the actress Gene Tierney and Elle dubbed Murphy "The blonde Gene Tierney".
